Things the 'jhead' program can extract from an Exif file:
- Integral low-res Exif thumbnail
- Shutter speed
- Camera F-stop number
- Flash used (yes/no)
- Focus distance (some digital cameras store this element - very
interesting)
- Focal length (most zoom cameras store their zoomed-to focal length)
- Equivalent 35mm focal length (Calculated from focal length, CCD size,
and CCD resolution)
- Image resolution
- Time and date picture was taken
- Camera make and model
